Pomanga, choyamba ntchito amakina othamanga kwambiri pamsewu wowombazotsukira kuwomba mumsewu pamwamba dothi ndi mchenga ndi zinyalala zina kuonetsetsa kuti pamwamba pa msewu mulibe lotayirira particles, fumbi, phula, mafuta ndi zinyalala zina zimene zimakhudza khalidwe chizindikiro ndi youma.Kenako, molingana ndi zofunikira za kapangidwe ka uinjiniya, gwiritsani ntchito makina olipira okha ndikuthandizira pamanja kulipira mzere mugawo lomangamanga, ndiyeno gwiritsani ntchito kupopera mbewu mankhwalawa mopanda mpweya wopanda mpweya kuti mupope mtundu womwewo ndi kuchuluka kwa wothandizila undercoat monga kuvomerezedwa ndi mainjiniya oyang'anira (Base mafuta), chotchingira chikawumitsidwa, gwiritsani ntchitomakina odzipangira okha otentha osungunukakapena makina ojambulira otentha osungunuka m'manja kuti agwiritse ntchito zolembera.

Kufalikira kwa mikanda yagalasi kuyenera kufalikira pamzere wodziwika pansi pa kupanikizika kwa 0.3kg/m malinga ndi momwe injiniya woyang'anira amafunira.Pomanga, kutentha kwa mumlengalenga sikuyenera kutsika kuposa 10 ℃.Utoto ukatenthedwa mu ketulo yotenthetsera kapena mbiya yotenthetsera ya makina ojambulira, kutentha kuyenera kuwongoleredwa mkati mwa mtengo wa kutentha womwe wafotokozedwa m'buku la malangizo a utoto, ndipo usakhale wotsika kapena wapamwamba kuposa malire otsika kapena apamwamba Kutentha, chifukwa. ndichofunda chotentha chosungunukazomwe zimagwiritsidwa ntchito mu polojekitiyi zimatumizidwa kunja kwa hydrocarbon resin zakuthupi, nthawi yake yosungunuka isapitirire 6h.Ntchito yonse yomangayi idzachitika panthawi yomwe Party A idasankhidwa, ndipo ntchitoyo iyenera kuyimitsidwa kwakanthawi pakagwa mvula, fumbi, mphepo, ndipo kutentha kuli pansi pa 10 ° C.

Pantchito yomanga, njira zomwe zakhazikitsidwa zisanamalizidwe, ziyenera kutsatiridwa, njira zofananira zachitetezo chapamsewu ziyenera kukhazikitsidwa, zizindikiritso zochenjeza ziyenera kukhazikitsidwa, magalimoto ndi oyenda pansi aletsedwe kwambiri kuti asadutse malo ogwirira ntchito, ndipo zokutira ziyenera kupewedwa. kunja kapena kupanga zinyalala.

Njira zenizeni zomangira zolembera zamsewu ndi izi:

1. Sesani pamseu: Choyamba, perekani chithandizo chamankhwala pamsewu ndikuchotsa zinyalala.Ngati msewu zinyalala ndi zovuta kuchotsa ndi njira ochiritsira, ntchito zitsulo burashi mtundu msewu pamwamba zotsukira kuti nkomwe kuchotsa zinyalala msewu, ndiyeno ntchito mphepo msewu zotsukira kuwomba zinyalala msewu, ndipo potsiriza kukumana msewu kuyeretsa mfundo zimene zikugwirizana. zofunikira zolembera.

2. Kukonzekera kwa zomangamanga: mkati mwa gawo la ntchito yomanga, malinga ndi zojambula zomanga ndi zofunikira zaumisiri, kuyeza ndi kukhazikitsa, kuti athe kuyendetsa kayendetsedwe ka ntchito yomanga.Mukamaliza kukonza, chitani zoyeserera zoyambira.Pambuyo pakuwunikira koyambirira, mainjiniya oyang'anira adzafunsidwa kuti achite kuvomereza.Njira yotsatira ikhoza kuchitidwa pokhapokha kuvomereza kwadutsa.

3. Kupopera mankhwala a undercoat agent (mafuta oyambira): Malinga ndi mtundu ndi njira yopoperapo mankhwala a undercoat agent yoyesedwa ndikuvomerezedwa ndi mainjiniya oyang'anira, gwiritsani ntchitokupopera mpweya wopanda mpweyakupopera mankhwala a undercoat molingana ndi njira zogwirira ntchito.

4. Pambuyo pake ndondomeko yomangamanga: gwiritsani ntchito makina osindikizira otentha osungunuka okha kapena makina osindikizira otentha osungunuka ndi zipangizo zina kuti amange motsatira ndondomeko zoyendetsera ntchito.

5. Ikani zikwangwani zochenjeza kuti magalimoto ndi oyenda pansi asaphwanye zikwangwani zomanga.
